Apparatus for fixing printed circuit board of refrigerator

ABSTRACT

In an apparatus for fixing a printed circuit board of a refrigerator, since a printed circuit board is slid to be coupled with or separated from the inside of a support plate fixed at a lower portion of a refrigerator main body, the printed circuit board can be readily and conveniently replaced.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an apparatus for fixing a printed circuit board of a refrigerator, and particularly to an apparatus for fixing a printed circuit board of a refrigerator for fixing a printed circuit board installed at a refrigerator main body so as to control a refrigeration function.

[0003] 2. Description of the Background Art

[0004] Lately, as a refrigerator is multifunctionalized, a size and an installation position of a printed circuit board for controlling a refrigeration function is importantly considered.

[0005]FIG. 1 is a perspective view showing a conventional refrigerator.

[0006] As shown therein, at the conventional refrigerator, a fixing apparatus 10 covering a printed circuit board 2 is coupled with an upper portion of the refrigerator main body 1 (or rear surface thereof) by a volt 11. At a lower portion of the refrigerator main body 1, a lower cover 3 is installed.

[0007] However, in the conventional refrigerator, the fixing apparatus is installed at the upper portion of the refrigerator main body (or a rear surface), and the printed circuit board is mounted in the fixing apparatus. For this reason, in case of repairing or replacing the printed circuit board, since volt has to be fully unthreaded in order to disassemble the fixing apparatus, it is difficult to repair and replace the board, and it takes much time to terminate those works.

SUMMARY OF THE INVENTION

[0008] Therefore, an object of the present invention is to provide an apparatus for fixing a printed circuit board of a refrigerator capable of being easily and conveniently replaced and repaired without moving a refrigerator main body since the printed circuit board is slid to be coupled with and separate from the inside of a support plate fixed at a lower portion of the refrigerator main body,

[0009] To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided an apparatus for fixing a printed circuit board of a refrigerator according to the present invention includes a support plate installed at a lower portion of a refrigerator main body so as to slidably receive the printed circuit board; and a support plate coupling means for fixing the support plate to the lower portion of the refrigerator main body.

[0010] The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0020]FIG. 2 is a front view showing installation of an apparatus for fixing a printed circuit board of a refrigerator according to the present invention. FIG. 3 is a disassembled perspective view showing an apparatus for fixing a printed circuit board of a refrigerator according to the present invention, and FIG. 4 is an assembled perspective view showing an apparatus for fixing a printed circuit board of a refrigerator according to the present invention. FIG. 5 is a side view showing an apparatus for fixing a printed circuit board of a refrigerator according to the present invention, and FIG. 6 is an enlarged longitudinal sectional view showing a main part.

[0021] As shown therein, an apparatus for fixing a printed circuit board of a refrigerator according to the present invention includes a support plate 110 installed at a lower portion of a refrigerator main body 1 so as to slidably receive the printed circuit board 2; a volt hole 121 formed at both sides of the support plate in order to fix the support plate 110 to the refrigerator main body; and a volt 122 coupled to the volt hole 121.

[0022] The support plate 110 includes a receiving portion 111 where the printed circuit board 2 is received; and a flange portion 112 bent and formed at both sides of the receiving portion 111.

[0023] Preferably, the support plate 110 is positioned at an interval of 30 mm between itself and a bottom surface S within the house, and a surface of the support plate 110 is waterproofed.

[0024] At an inner bottom surface of the support plate 110, two guide protrusions 111 a are formed in a moving direction of the printed circuit board 2.

[0025] The guide protrusion 111 a can make a movement of the printed circuit board 2 smooth, and, since generating an interval between the printed circuit board 2 and the inner bottom surface of the support plate 110, makes the printed circuit board 2 received in the receiving portion 111 of the support plate 110 readily and conveniently pulled out.

[0026] The printed circuit board 2 is a board where a circuit element for controlling a refrigeration function is integrated. At the back surface of the board, a connection terminal 2 a is formed.

[0027] At an inner surface of a lower portion of the refrigerator main body 1, a power terminal 1 a corresponding to the connection terminal 2 a is installed. Accordingly, if the printed circuit board 2 is inserted into the support plate 110, the connection terminal 2 a of the printed circuit board 2 is automatically connected to the power terminal 1 a.

[0028] At the lower portion of the refrigerator main body 1, a lower cover 3 for covering the support plate 110 is installed. For a fine view, the lower cover 3 covers the support plate 110, and makes the support plate 110 invisible in a view of the front of the refrigerator main body 1.

[0029] Herein, the lower cover 3 is generally installed at the lower portion of the refrigerator main body 1, and is coupled to the main body 1 through a volt (not shown).

[0030] Generally, at the printed circuit board 2, heat is generated, and thus the support plate 110 is heated by this generated heat. Therefore, the front surface of the support plate 110 being in contact with cold air within a house, may be covered with dew, and thus the printed circuit board 2 may break down since this dew can cause a short circuit.

[0031] In order to prevent this break down, an adiabatic portion 110 a is formed at a portion at which the lower cover 3 and the support plate 110 are in contact with each other, that is, at the front surface of the support plate 110.

[0032] In the apparatus for fixing the printed circuit board of the refrigerator according to the present invention constructed as above, a volt 122 is coupled at the volt hole 121 of the flange 112 of the support plate 110. In this manner, the support plate 110 is fixed to the lower portion of the refrigerator main body 1.

[0033] In a state that assembling of the support plate 110 has been terminated, if the printed circuit board 2 is inserted into the receiving portion of the support plate 110, the connection terminal 2 a is connected to the power terminal 1 a.

[0034] At this time, the printed circuit board 2 is smoothly inserted into the receiving portion 111 of the support plate 110 by the guide protrusion 111 a.

[0035] The lower cover 3 is fixed to the lower portion of the refrigerator main body 1 by a volt (not shown), and prevents the support plate 110 from being exposed to the outside.

[0036] When the printed circuit board 2 is replaced because of degradation and a break down thereof, first of all, a volt (not shown) is unthreaded, and thus the lower cover 3 is separated from the refrigerator main body 1.

[0037] Thereafter, if the printed circuit board 2 is pulled out, using a gap between the printed circuit board 2 and the support plate 110, the printed circuit board 2 is separated from the receiving portion 111 of the support plate 110, and simultaneously, the connection terminal 2 a is separated from the power terminal 1 a.

[0038] At this time, the printed circuit board 2 is smoothly separated from the receiving portion 111 of the support plate 110 by the guide protrusion 111 a.

[0039] As so far described, in the apparatus for fixing the printed circuit board of the refrigerator according to the present invention, without moving a refrigerator main body, the printed circuit is slide to be coupled with or separated from the inside of the support plate fixed at the lower portion of the refrigerator main body. For this reason, the printed circuit board can be replaced more readily and conveniently.
